Metastasis causes the death of patients with solid cancers. The core molecular mechanism of metastasis remains largely unknown. The research of Dr. Zhang “John” Weihua’s laboratory focuses on understanding the following metastasis-related molecular mechanisms:

1. The tyrosine kinase independent function of the epidermal growth factor receptor, EGFR.

2. The impact of organ microenvironment on the energy metabolism of cancer metastasis.

3. The role of intracellular ATP levels of cancer cells in the development of cancer metastasis.
